Linux on Nokia N70

Hello everyone, I hope I could find supporting in my project:
http://n70linux.wordpress.com/

It is theoretically doable: http://n70linux.wordpress.com/hwspecs

The most tempting options however are NOT-doable:

=A0* Loading uBoot from Symbian, using files from Siemens SX1 linux
project http://sourceforge.net/project/showfiles.php?group_id=3D166282 :
This failed - http://n70linux.wordpress.com/2009/06/17/trying-ubootloader:
=A0* ubootloader-1.5 quit with leave code=3D-2. ubootloader is,
unfortunately, a closed source
(http://forum.oslik.ru/viewtopic.php?t=3D27061#242186), no
documentations

Failed probably because that this U-Boot is patched for the Siemens SX1

Another possible failing attempt would be:
=A0* Flashing the U-Boot with JTAG directly into N70's flash memory
because:
=A0* I could find no Nokia S60 series JTAG pin documentation
=A0* N70 is a BB5 phone, and it is protected from JTAGging
(http://n70linux.wordpress.com/hwspecs/#JTAGing), unlocking etc.

Possibly doable approaches could be:
=A0* Spying the USB communication when Nokia's Firmware Updater is in actio=
n
=A0* Patching the U-Boot for N70 (referencing S60?, OMAP 1710?)
=A0* Decrypting the flash of BB5 in a way it was done with DCT4
(http://forum.gsmhosting.com/vbb/showthread.php?p=3D991474#post991474)

=A0* will try the http://users.net.yu/~dejan/download/bb5.zip, hoping
it will also decrypt, not only unlock this BB5 phone

=A0* Patching the flash memory according to this thread:
http://forum.oslik.ru/viewtopic.php?t=3D27061#242665
=A0* Disassembling ubootloader

Suggestions from you -- the community out there -- are more than appreciate=
d!
